I live in the PA where emissions are pretty strict. I got my DMH EEC and I want to put it in place of the res. A couple people I have talked to said the resonator holds some emissions properties. I just need to know if taking it out is gonna flip the CEL on. If so its gonna fail inspection.

The resonator is only for noise control.

from what i was told by everyone when i lived there you need the res for emissions

That's odd because Haulin is right, It's only used for noise control. Some cat backs don't even come with the res.

Completely 100% false.

Just have it closed, it'd be one hell of an exhaust leak LOL

i always thought it was for sound to but thats what almost every place told me when i did the res delete on my gtp that it wouldnt pass but i still did it anyway
